Drainage assembly

Abstract

An insulated structure includes a wrapper that defines a first aperture. A liner defines a second aperture and is coupled to the wrapper. A negative pressure is maintained between the wrapper and the liner. A drainage assembly extends between the liner and the wrapper and is disposed within the first aperture and the second aperture. The drainage assembly includes a flexible body that has a plurality of flexures, first and second surfaces, and an opening that is defined between the first and second surfaces. The flexible body has at least one notch that is defined on the first surface that extends from a portion of the opening. A drainage tube extends through the opening that is defined by the flexible body and is operably coupled to the flexible body. The drainage tube includes at least one flange disposed within the at least one notch of the flexible body.

What is claimed is: 
     
       1. A drainage assembly for an insulated structure, comprising:
 a flexible body defining a drainage opening and a notch extending from the drainage opening, the flexible body including a projection proximate to the drainage opening; 
 a tube having an entry end and an exit end, wherein the tube is disposed within the drainage opening, the tube including a flange disposed within the notch of the flexible body; and 
 a locking feature having a central void and disposed proximate the exit end of the tube and rotatable between a first position and a second position, wherein the locking feature is coupled to the projection and engaged with the tube in the second position. 
 
     
     
       2. The drainage assembly of  claim 1 , wherein the tube further includes locking projections extending outwardly from the tube proximate the exit end. 
     
     
       3. The drainage assembly of  claim 2 , wherein the locking feature includes inclined edges disposed within the central void of the locking feature, and wherein the locking projections of the tube selectively engage the inclined edges in a locked configuration. 
     
     
       4. The drainage assembly of  claim 1 , wherein the locking feature includes a clip having tabs that selectively couple the locking feature to the projection of the flexible body. 
     
     
       5. The drainage assembly of  claim 1 , wherein the body further includes a pull tab proximate to the projection. 
     
     
       6. The drainage assembly of  claim 1 , wherein the tube defines locking projections that engage the locking feature in the second position. 
     
     
       7. An insulated structure, comprising:
 a wrapper defining a first aperture; 
 a liner defining a second aperture and coupled to the wrapper, wherein a negative pressure is maintained between the wrapper and the liner; and 
 a drainage assembly extending between the liner and the wrapper and disposed within the first aperture and the second aperture, the drainage assembly comprising:
 a flexible body having a plurality of flexures, first and second surfaces, and an opening defined between the first and second surfaces, the flexible body having at least one notch defined on the first surface that extends from a portion of the opening and a recess defined on the second surface with a projection proximate to the recess; and 
 a drainage tube extending through the opening defined by the flexible body and operably coupled to the flexible body, the drainage tube including at least one flange disposed within the at least one notch of the flexible body. 
 
 
     
     
       8. The insulated structure of  claim 7 , wherein the drainage assembly includes a locking feature rotatably coupled to the drainage tube and disposed in the recess defined by the second surface of the flexible body, and wherein the locking feature selectively couples to the projection of the flexible body. 
     
     
       9. The drainage assembly of  claim 8 , wherein the locking feature includes inclined edges and the drainage tube includes locking projections selectively engaging the inclined edges of the locking feature in a locked position of the locking feature.
